I know other people have gone through the US census, but I don't know if it has ever been posted. I'd like to save others the trouble. I've covered Thrift, but still want to go through it for Frith. Eventually hope to cover some later censuses also. (Anyone want to volunteer? Anyone already done this?) Also, I want to do the same in England.

Some US Censuses are posted here;
http://www.census.gov/prod/www/abs/decennial/index.htm
The ones I've seen are in NONsearchable PDF format, which means you have to open the index for the state, find what page your person of interest is listed on, open that document, then manually look through that page.

The 1790 census is there for all 12 states EXCLUDING Georgia. I found Thrifts listed ONLY in the indices for Maryland, North Carolina, South Carolina, and Virginia. Remember that many people were completely missed by these censuses, if a name isn't here it doesn't mean they weren't alive at the time.

The Virginia entries are subtitled "Records of the State Enumerations: 1782 to 1785"
Does this mean people listed alive 1782-1785 but weren't necessarily still alive in 1790?
